## Questions

### Who runs investment decisions at Mesco?

Joel Mesznik, the founder, leads the firm. Mesco was created in 1990 following his career as a Wall Street investment banker. On individual transactions, Mesco brings in experienced sector professionals to supplement its in-house judgment. The firm discloses no additional partners or investment committee members.

### How does Mesco source proprietary deal flow?

Mesco relies on long-standing relationships with U.S. and international families, endowment funds, venture capital firms, and previous transaction partners. The firm publicly states it focuses on a limited number of transactions simultaneously. Its sourcing is linked to its track record and the Rolodex of its founder, who has been active in cross-border transactions since the early 1990s.

### Does Mesco participate in fund commitments or only direct deals?

Mesco primarily invests in direct deals through single-purpose investment vehicles. Its historical track record includes advisory work on a Luxembourg-domiciled open-end healthcare fund, Pharma/wHealth, which it helped structure and continues to consult. There is no public evidence that Mesco acts as a limited partner in blind-pool funds managed by third parties.

### What is Mesco's known posture on co-investments alongside external GPs?

Co-investment is Mesco's standard operating method. The firm structures direct investments through affiliated vehicles and almost always co-invests alongside external partners. On the Healthcare Services side, its co-investment activity includes Amylin Pharmaceuticals, Tularik, and Memory Pharmaceuticals, though many of these holdings are dated and current status is unconfirmed.

### Is Mesco still active, and what has its recent deal cadence looked like?

Mesco maintains a public website detailing its historical transactions. The most recent verifiable investment include Alignable and Estimize, though exact dates of recent closes are not publicly posted. The firm continues to consult the Pharma/wHealth fund and lists open-investment real estate holdings as of the latest website update.
